595 too
1 too and vety
Too is different from very - too means 'more than enough', 'more than necessary' or 'more than is wanted'. Compare:
- He's a very intelligent child.
He's too intelligent for his class - he's not learning anything.
- It was very cold, but we went out.
It was too cold to go out, so we stayed at home.
2 too and too much
Before adjectives without nouns and before adverbs we use too, not too much. You're too kind to me. (NOT Yint'Fe 166 m'tteh febttl 16 me.)
I arrived too early. (NOT I afflueti 166 m'tteh edrly.)
Too much is used, for example, before nouns. For details see 596. I've got too much work.
3 modification: much too, far too etc
Expressions which modify comparatives (see 140) also modify too.
much too old (NOT tIet}' t66 61tt) a lot too big
far too young
a little too confident a bit too soon rather too often
4 not used before adjective + noun
Too is not normally used before adjective + noun.
I put down the bag because it was too heavy. (NOT ••. the 160 hea~ bag.) She doesn't like men who are too tall. (NOT She MJ8Stt't like t66 Mil men.) Let's forget this problem - it's too difficult. (NOT ••• #lis 166 tlijJieflJt
I'fflblem. )
In a rather formal style, too can be used before adjective + a/an + noun (see 14). Note the word order.
It's too cold a day for tennis.
5 tOO . •. + infinitive
We can use an infinitive structure after too + adjective/adverb. He's too old to work. It's far too cold to go out.
We can also use an infinitive structure after too much/many. There was too much snow to go walking.
If the infinitive has its own subject, this is introduced by for (see 291). It's too late for the pubs to be open.
There was too much snow for us to go walking.
6 too salty to drink, etc
The subject of a sentence with too can also be the object of a following infinitive. (For more about this structure, see 284.4.) Object pronouns are not normally used after the infinitive in this case.
